" o ALL WHOM IT MAY CONCERN:

Be it known that I, Hsn'vnv 'WnBs'aEn, of Cambridge, in, the county of Lamoille, and State of Veruiont,

'hav e invented certain Improvements. in Whifile-Trees;. and-I do heieby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and the letters of reference marked thereor Y b I Figure 1, perspective,.showing back and under side. Figure 2, transverse section on line A'B, fig. 3. Figure 3, longitudinal section on line C'D, fig. 2.

To enable others skilled inthe art to'make and use my invention, I will proceed to describelits'constructionend'operation.

he improvements that I claim consist in the extended band A, with grooves Bend); the groove C preventing the swelling or other action of the wood afi'ecting the 'play or operation of the cast-oil'D;'the groove B" acting as a guard to the spring-lever E, and preventing'th samcifr'om being accidentally opened or' sprung;

false acting asa guard against ice and mud, thereby rendering the present device practicable, wherein the other, as patented by H. A. Webster, under date of 29, 1855,- was impracticable. V I claim also thetfurther 'impvo'i'ement in the form of the cast-ofl', and the form and position of the spring-lever catch E, as also the inanner of fastening the east-cfi' Di 7 i l I In the construction, I z etain the ferns and action ofthe springF, asalso the draught-pin G, allas described in Letters Patent granted as above. The remainder of the'tlevice, 01'' that partthat I claim as myimprovement, is constructed substantially in the manner shown. 7

In the operation of my device, it is in all respects similar to the patent granted as above, except that I add to the spring-lever catch E the thumb-plate H. for the purpose of. opei'atingthe'lev er with thehand, and independent ofthe cord. I i V l What I clailn, and de'sireto secure-by Letters Patent, is.- n i The plate A, ivithits grooves B and C, the spring-lever E, cast-ofi D; the spring-F, and draught-pin G, all arranged and operated as shown and described. 7 I
